The present invention relates to a cable tray section which allows being successively coupled to another tray section (1) having similar features, without needing accessories or angle requirements on the horizontal plane, comprising longitudinal metal wires (10); U-shaped transverse metal wires (20); at least one anchoring element (30) installed between the longitudinal wires (10), attached to the last and next to last transverse wires (20), and comprising a single metal wire (31) close to the next to last transverse wire (20); and a pair of straight sections (32, 32′) parallel to one another; where the upper straight section (32′) projects with respect to the last transverse wire (20), forming an S-shaped section (33) perpendicular to the straight sections (32, 32′), such that there is established a free space (40) between the last transverse wire (20) and said S-shaped section (33); said space (40) having a dimension corresponding to the thickness of a transverse wire (20).
